A lot of GMO talk is often about the Seralini and other flawed studies. Some people claim that independent research on the safety of GMO's is lacking and others ask where the research is. I thought it might be useful to point out that GMO's is one of the most studied topics in science and that it is fairly easy to find studies that show how safe they are.
http://www.ncbi.nlm.nih.gov/pubmed/18328408Overall, the results of these studies suggest that the GM rice may be safe for use as a dietary ingredient when it is used at up to 50% in the diet on a subchronic basis
http://www.ncbi.nlm.nih.gov/pubmed/16326439With respect to the detection of potential unintended effects in whole GM food and feed, it is unlikely that substances present in small amounts and with a low toxic potential will result in any observable (unintended) effects in a 90-day rodent feeding study, as they would be below the no-observed-effect-level and thus of unlikely impact to human health at normal intake levels. Laboratory animal feeding studies of 90-days duration appear to be sufficient to pick up adverse effects of diverse compounds that would also give adverse effects after chronic exposure. This conclusion is based on literature data from studies investigating whether toxicological effects are adequately identified in 3-month subchronic studies in rodents, by comparing findings at 3 and 24 months for a range of different chemicals.

Lastly, here is a link to a downloadable spreadsheet with 1,783 studies.From these results, it can be concluded that the GM potatoes Spunta line (G2 and G3) with Cry V gene are confirmed to have nearly the composition and biochemical characteristics as non-GM potato Spunta.
